This PR adds support for running make check job on Power hardware.

Can one of the admins verify this patch?

[jmundack]

can we add in some details on why we are adding this in?

also - do we have enough runners in the lab for this?

I've added some detail on what this does in the description.
As for the runners, they will be provided by my team at IBM.
We had a discussion a while back with some folks from the Ceph engineering team about running make check on power. We were told that they'll be fine with it as long as we maintain the code and hardware for it.
This PR is a Draft since we still have some things to fix on our end.

thanks for the context.!

can this be like a weekly job rather than a PR check? especially in the beginning while resources are flushed out (gear as well as effort to maintain this)

[anshuman-agarwala]

Sure! I've changed the job cadence to weekly.
